2. In an experimental dataset, researchers often encounter 'outliers'-data points that deviate significantly from the established trend or theoretical expectation. Critically evaluate the scientific and ethical implications of data exclusion. Specifically, discuss why the practice of omitting outliers without transparent justification (as suggested in options A and B of the original multiple-choice prompt) undermines the validity of research. In your response, address how a researcher should systematically investigate these anomalies and what their presence might reveal about the experimental design or the phenomenon under study.
